Comments
A second species Rungaperla campbelli (Illies)issemi-terrestrial,
livingindamphabitatsbutnotunderwater(Illies,1963).
NeverthelessitwasfoundinstreamsamplesbyJoy&Death(2000).
Its cerci are much shorter than those of R. longicauda(i.e.,about
aslongasthelasttwoabdominalsegments)andthegillsare
rudimentary.MaximumlengthofR. campbellilarvaeisabout20mm.
